Thank you for purchasing this McElroy product.
The McElroy® MegaMc® Pipe Stand allows efficient alignment
of pipe in the fusion machine jaws. Using the pipe stand's
34" vertical and 24" lateral adjustments, the pipe is efficiently
aligned with the fusion machine jaws. Aligning the pipe
quickly reduces the overall cycle time for the joint, increasing
productivity. Good alignment in the jaws means less stress
on the fusion machine, easier to close jaws and less hi-low
mismatch.
With reasonable care and maintenance, this machine will give
years of satisfactory service.
Before operating this machine, please read this manual
thoroughly, and keep a copy with the machine for future
reference. This manual is to be considered part of your machine.

Equipment Safety
Pipe Handling Safety
Do not position yourself under supported
or raised pipe or near the end of the pipe.
Pipe could travel uncontrolled on the rollers
in either direction and cause serious injury
or death.
In order to minimize the potential for the pipe to travel
uncontrolled, keep the pipe level when it is placed on the
rollers of the fusion machine and on the rollers of the pipe
stand(s). Hold pipe securely by either clamping in the fusion
machine jaws or by other means.
NOTICE: Do not leave stand unattended while HPU is
running. When not operating the pipe stand, turn off the
HPU to prevent accidental or unintentional movement of the
stand.
IMPORTANT: Engine does not need to be running to hold
load. However, do not leave raised pipe unattended as the
hydraulic pressure may bleed off over time and lower the
load.

Units With Hydraulics
It is important to remember that a sudden hydraulic oil leak
can cause serious injury, or even be fatal if the pressure or oil
temperature is high enough.
Escaping fluid under pressure can penetrate the
skin causing serious injury. Keep hands and
body away from pinholes which eject fluid under
pressure. Use a piece of cardboard or paper to
search for leaks. If any fluid is injected into the
skin, it must be immediately removed by a doctor
familiar with this type of injury.
Unwanted movement of the machine could result
in serious injury or damage to machine. Unwanted
movement of the machine may take place if switches
do not match machine state when the machine power
is turned on.
NOTICE: Wear safety glasses, and keep face clear of area when
bleeding air from hydraulic system to avoid spraying oil into eyes.
TX03007-04-18-16
WR00078-4-8-93

Operating On A Grade
Never operate the pipe stand on a grade
steeper than 20 % (A 2 foot elevation
change in 10 feet). Pipe could fall off the
rollers or pipe stand could tip causing
serious injury or death.
Place pipe stand on as level ground as possible.
If it is necessary to operate machine on unlevel grade, make
sure that the ground is stable. Some unstable conditions include
ice, snow, mud and loose gravel.

Operation
Starting the HPU
Check that the fuel tank is full of clean unleaded gasoline. Check
that the air cleaner element is clean.
Make sure the fuel cut off valve under the air cleaner is open (A). It
is open when the black lever is in line with the fuel line. Set the red
throttle lever on the engine to start.
Pull the starter grip lightly until you feel resistance then pull briskly
a full stroke. Return the starter grip gently (do not allow it to snap
back against the engine).
After the engine starts, gradually move the throttle to fast (F) position
as the engine warms up. To restart a warm engine put the throttle
lever at fast (F).
To stop the engine, move the red throttle lever to the stop position.
The engine should be started each time the Pipe Stand is to be
adjusted and then stopped.
To stop the engine at the end of the work day, put the lever at the
slow position (S). Turn the black fuel valve lever to the off position
(perpendicular to the fuel line).

Operation
Stand Placement
Placement For Use On Movable Jaw Side Of Fusion Machine
Place the pipe stand to the right of the fusion machine so that the free stick of pipe (clamped in movable jaws) will
be supported by the stand. Place the pipe stand controls on the same side as the fusion machine’s controls so that
the operator does not have to cross the pipe. Place the pipe stand at least half the length of a stick of pipe away
from the fusion machine. This is so the pipe won’t teeter and lift off of the fusion machine jaws. This also allows lifting
equipment carrying a piece of pipe at its center to go between the fusion machine and Pipe Stand to load the pipe.
Center the base of the stand (not the trolley rollers) on the fusion machine jaws centerline. This allows the 24” of
lateral adjustment to be used 12” on either side of center.
Using proper lifting equipment, place the stick of pipe on the movable jaws and pipe stand rollers so that the end of
the pipe extends from the inner jaw the amount required for a proper face off.
Do not position yourself under supported or raised pipe or near the end of the pipe. Pipe could travel
uncontrolled on the rollers in either direction and cause serious injury or death.
NOTICE: Take care not to impact the fusion machine or pipe stand with the pipe. The pipe is heavy and can do
damage to the machines, especially raised jaws, facer and heater.
Placement On Fixed Jaw Side Of Fusion Machine
Place the second pipe stand to the left of the fusion machine so that the fused stick of pipe coming out of the machine
rests on it. Place the pipe stand controls on the same side as the fusion machine’s controls so that the operator does
not have to cross the pipe.
Additional pipe stands or rollers may be required to adequately support the length of fused pipe exiting the fixed jaw
side of the fusion machine.

Align Pipe with Fusion Machine
To align the pipe in the fusion machine, adjust the pipe stand so that the pipe fits inline with the jaws or inserts. Once
the adjustment is complete, stop the HPU engine.
On very uneven terrain or with bent pipe, the pipe stand may not go low enough to align the pipe in the fusion
machine jaws. Possible options for correcting alignment:
• Rotate the pipe so it bows sideways or up rather then down.
• Lower the pipe stand by digging out underneath it.
• Raise the fusion machine up with stable blocking.
On very uneven terrain or when using small pipe in a larger fusion machine, the pipe stand may not go high enough
to align the pipe in the fusion machine jaws. Possible options for correcting alignment:
• Raise the pipe stand with stable blocking.
• Dig out where the fusion machine is to lower it in relation to the pipe stand.
Operation
Small diameter pipe in a large
MegaMc fusion machine may be too
high for pipe stand to reach.
Large diameter pipe in a large MegaMc fusion
machine, the pipe stand may not go low enough
to align the pipe in the fusion machine jaws.
Block up stand as needed.
Dig out the stand as needed.

How to use this chart:
The MegaMc Hydraulic Pipe Stands are intended for use with the MegaMc fusion machines. The 8-36 pipe stand
is best matched to the 824, T630, 1236 and T900 fusion machines. The 36-65 pipe stand is best matched to the
1236, T900, 1648, 2065 and 1600 fusion machines. There is some capability overlap so this chart details all
the combinations of pipe size and MegaMc fusion machines that can be used with the 8-36 and 36-65 MegaMc
Hydraulic Pipe Stands.
To determine which pipe stand to use, locate the pipe size at left of chart and fusion machine at top of chart. Where
the two intersect will fall within the operating envelope of either the 8-36 or 36-65 pipe stand or both. The chart is
based on the fusion machine and pipe stand being on level ground. Uneven ground will shift the effective operating
envelopes. For heavy wall pipe, ensure that the weight of a stick of pipe does not exceed the pipe lift capacity of
9,000 lbs. for 8-36 and 16,000 lbs. for 36-65.
To reach some small pipe sizes in a 65 fusion machine, the pipe stand must be blocked up.
